Dosimetric control system for the IBR-2 reactor

In 2010 the modernization of the dosimetric control system for the refurbished IBR-2 reactor was completed. The system represents a module of rate counters that accept pulses from various detectors. The module is designed in CAMAC standard with USB interface. The software part includes a new package of programs for real-time dosimetric control, which runs under Windows XP. The system makes it possible to control the radiation situation at personnel work places, in technological premises and atmospheric emissions. Simultaneously, the control system collects and sorts the data flow, analyzes it, and stores the information into archive. An important part of the new control system is full visualization of radiation levels in real time. In case of danger, when radiation safety limits are exceeded, the system issues audio, graphical and textual warnings. The present paper describes the structure and features of the dosimetric control system for IBR-2.
